Two things to try:
- Trash your prefs http://blogs.adobe.com/genesisproject/2009/11/having_weird_behavior_with_an.html
- Export a portion of your timeline only (say 10 minutes) and see if that completes correctly.
Also, check that you have adequate free space on your HDD. First, you need the space for the exported file, and then also space for the very large "working files," that PrPro produces for the Export. This has gotten many in the past. They'll have enough free space for the Export file, but not enough room for the working files.
I will definitely try this. Thanks for the info.
I will check this out. I think I have enough space but one never knows. Thanks for the info.
